Recently cut about 5 acres of subdivision lots with the super Z. These were open lots with nothing on them. Had a blast. What an awesome machine. the power is really felt when you put it wide open. It did a very good job. No way you would want to run wide open in a small yard or could. But if you have a lot of open property to cut this it the one to get. Way too much fun to be work.

Pumps and wheel motors are larger, and the hydraulic system also has a hydro cooler for added cooling.
And of course the Super Z's are faster units (15mph)
The Super Z's also offer some larger engine options in some models.

Suspention seat,oil cooler,spoiler,and bigger pumps.....I purchased a SUPER Z in Nov.,Love running that machine.........Don't want to quit moweing/Ist cut does the job,but I usually go over it 5 or 6 times..cause I can't quit mowing
